Sealite strives to provide straightforward terminology to assist you in your selection. Here’s what you need to know, and why it’s important. Term Explanation Overall Height Total buoy height, including any external counterweight. Height of the buoy above the water line in a typical installation. Freeboard may Nominal Freeboard vary slightly due to differences in water density, mooring load, and current speed. Length of the buoy that is under water. Like Freeboard, draft can vary due to Nominal Draft particular installations. Visible area of a buoy, calculated from freeboard and the diameter of the buoy. Visual Area (or Exposure) Visual Area is a key measure of the visibility of a buoy to mariners. Submergence Amount of weight necessary to sink a buoy one inch (or centimeter). 8 Maximum weight of the mooring load for a buoy to still achieve Nominal Maximum Mooring Load Freeboard. 9 8 7 6 5 4 3 2 1 Wall Thickness Thickness of the rotationally molded plastic wall. G Overall width of the buoy. May be more than one [diameter] if float collar type of Diameter buoy. Reserve Buoyancy Amount of product weight and the required buoyancy required to keep it afloat.
